CAR-ROOF.

1,265,523. Specification of Letters Patent. Patented May 1918,Application filed September 1, 1914. Serial No. 859,675.

To all whom it may concern:

Be it known that I, THOMAS NATHAN RUS- SELL, a, citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented. a new and useful Improvement in Car-Roofs, ofwhich the following is a specification.

The invention relates to outside metal roofs for freight cars, and hasin view several features of improvement which are partly improvements inthe roof patented to me December 2, 1913, No. 1,080,173. The presentimprovements are concerned with the formation of the seam by which theedges of the roof sheet, along the lines from the ridge to the eaves areunited with each other, in such manner as to make such seam a perfectwater seal, and also to make it strongly resistant to any superimposedweight, and at the same time to save metal in the roof sheet and in theseam. This result is attained by an improved conformation of theinterlocking edges of the roof sheets, so that the above advantageousresults are attained without necessitating the use of a separate,external seam cap. With, and as a confining and supporting means for,the said seam I employ an eaves seam clip of improved construction,arranged to confine the seam upon the top, and at the sides, and alsosupported from below, at the same time providing for the ready escape ofcinders, dust and moisture.

With such objects in view the invention consists in the parts andcombination thereof hereinafter set forth and claimed.

In order to make the invention more clearly understood there are shownin the accompanying drawings means for carrying the same into practicalefi'ect, without limiting the in1pr0vements,-in their usefulapplications, to the particular construction which, for the purpose ofexample, has been delineated. In said drawings- Figure l'is a plan view,partly broken away, of a car roof embodying the invention'.

"Fig. 2 is a vertical transverse section of :theroof', on line II-II ofFig. 1, a portion-of the same being broken away.

Fig. 3 is a. similar section of the eaves portion of the roof, on alarger scale, on line IIIIII of Fig. 6.

Fig. 4: is a transverse vertical section showing the ridge seam by whichthe roof plates are united.

Fig. 5 is a vertical section, on line V-V of Fig. 1, and partly brokenaway, showing portions of two of the roof sheets united to form a seam.

Fig. 6 is a side view of a portion of the roof, and car, the runningboard saddles being shown in section.

Fig. 7 is a perspective View of one of the roof sheets.

Fig. 8 is a perspective view, partly broken away, of a flashing whichmay be employed to underlie the eaves edge of the roof sheet and toextend down over the upper part of the fascia.

Fig. 9 is a perspective view of the same clip.

Referring to the drawings, 1 indicates the ridge pole of the car, 2 theside plates, 3 the carlines, here shown as consisting of angle ironsextending from side to side of the car and bent to conform to the slopesof the roof, and sustaining on their horizontal flanges filler bars 4 inthe nature of rafters, on which latter is sustained the top sheathing 5.The carlines, ridge pole and running board saddles 6 are united byvertical through bolts 7. The vertical flange of the carline is bentlongitudinally of the car as shown at 8, and is secured to the innerface of the side plate by a bolt 9. The horizontal flange of the earlineis bent upward along the inner face of the side plate, outward along thetop of the same, where it may fit in a suitable recess, and downwardagainst the outer face of the side plate, as shown at 10, where it issecured by a bolt 11.- The side sheathing is shown at 12, attached atits upper part to the outer face of the side plate, and recessed wherenecessary to receive the said flanges 10 of the carlines. The upper endof the upper partof the side sheathing is overlaid by the side fascia13, which is secured in place by the bolts and nails of the eaves seamclips. The eaves clips are shown at 14: and

may be of any form suitable for the purpose to confine the bent downeaves edges of the roof sheets.

15 indicates the roof sheets, each of which is formed at its ridge endso as to unite in a ridge seam with a contiguous roof sheet at theotherside of the ridge. A seam suit-, able for this purpose is showninwFig. 4, where one of the sheets is shown as'tormed with an outerinverted U-flange 16 bent away or outward from the main body of itssheet v and the corresponding sheet, at the other side of the ridge isformed with an inner inverted U-flange l7'bent toward and overhangingthe main body of the sheet by a return bend. The parts of this seam canbe united by mere superposition, and" do not interlock so as to requireto be Sl1Cl or telescoped together by movement longitudinally of theseam. This form of ridge seam can therefore be combined with side seams,extending from the ridge to the eaves, which completely interlockand'require to be telescoped together. There'is a tendency in theordinary form of ridge seam, in which a ill-bend, which-is bent away oroutward from'the top of the sheet,

issuperposed over a similar ill-bend, for the seam to be caused to openmoreor less and qgape by reason of the tendency of the sheets to workdown the inclined planes away from When the usual form of scamthe ridge.gapes in this manner a dashing rain will work through the seam in placesand cause leakage in the car. This difliculty is not experienced withthe form of ridgeseam which I employ and have illustrated, the action ofwhich is to catch rain which enters under the'return bend 17 andreturnit'npon the top of the roof sheet instead of eon-' ducting it fartherinto and between the parts of the seam, and such seam can also beemployed, as above explained, in combinaton wit'h said seams whichinterlock and Ithepartsofwhich must be teleseoped together. Thisstructure also forms a very strong, as well as water excluding,ridgeseam independent of any extended ridge cap. I however employ at thepoints where 7 four sheets meet, short four armed ridgecaps 18;, whichare confined by the running board saddles and have perforationsforduplicates of the sheets at the other side But my improved-side seam canbe used with the-ordi.nary=.;tormofridge seam. Atthe eaves endthe roofsheet is Mformed' with an extendedfiange 19' bent downwardly over thefascia, confined by theeaves-clips .14; Eachof the roof sheets isffQlmGCl along one of itstransverse edges (which extends transversely'offthe" car from' the eaves. to the ridge) with a dQubIe-I-flangeLQO;21,- and along its. other transverse edge with a triple flange 23, 24;The members 20 and 21 of the double flange are or may be parallel withone another and, are united at the top ;by a bend 25, and this flange isturned inwardly toward the bodyof the sheet so that the member2loverhangs the same. The menr bers 22 and 23 of the triple flange,together with a connecting arched portion 26, form a segment of a tube,such segment being considerably more than a l1alf,circle. The thirdflange member 24L extends upward within. the tube. The said parts are soproportioned that the double flange of one sheet may inter-loclr-witlr-the triple flange of-the next-sheet,- as best-seen =at the middleof Fig.5, so thatthe flange member 24 is included within the flangemembers 20 and 21, and the latter are included within the said tripleflange, the latter taking the place of and forming. in client a seam capwhich is capable of being supported from below by a-suitable eaves seamclip-.= Each roof sheet so formed is or'may be the counterpart of ever rother and yet comprisesa strong, leakproof and efficient seam cap Thecaves. seam clips aresshown. 211x27, each. of the same. being formed atits middle part with a hood. 28 which is nearly tubular, so as to fitaround and partly. beneathtne outerendsof the said caps or triplefianges22-, 23,126 From thishood.areextended inwardlya top :projection 29 whichholds the cap down'by an extendedbearing, and two bottom projections 30which fit atthe sides of and partly under the flange members 22 and 23;The: cap portions otthe roof sheets are thus closely confined in placeand supported fromvbe1ow,while the opposite edge-ofthe roof sheet-formedwith the double flange20, 21 is left free and. movable as may benecessary relative to all other parts, under the torsional movements ofthe roof. From-ether hood 28 the seam elipis curvedzoutwardlyand-downwardly to conform. to the flange,=19,= two contiguous ends ofwhichqflanges,.it;confines (Fig. 6), and its lowerpart-ibranched intoarms .31 which are perforated so that they maybe secured by nails .tothe fascia and side sheathing. The downwardlyextended part of the seamclip; is perforated to receive a bolt 82 which passes through .to theinner side of theside What I claim is:.
